How the Grade Calculator Works
This calculator figures out the score you need on your final exam so that your overall course grade reaches your target, given the exam's weight toward your final grade.
Formula
Worked Example
With a current grade of 85%, a desired final grade of 90%, and a final exam worth 20% of the overall grade, the required score is (90 − 85 × 0.80) ÷ 0.20 = 110%. Since that exceeds 100%, the target grade is not achievable through the exam alone — the student would need extra credit or should aim for a lower target grade.
Frequently Asked Questions
What does "current grade" mean here?
Your current grade is your grade in the course so far, before the final exam — typically the weighted average of all assignments, quizzes, and tests completed to date.
What if the required score is over 100%?
If the calculated required score exceeds 100%, it means your desired final grade is not achievable given your current grade and the exam's weight — you would need extra credit or the target grade should be lowered.
What if the required score is negative?
A negative or very low required score means you've already secured your desired grade based on your current standing — any reasonable score on the final will keep you at or above your target.
